In these contexts, cubic models are of special interest. Like in the ungauged case, some cubic models in gauged supergravity can be embedded into higher-dimensional theories describing the low energy limit of some string theory. In particular, the FI-gauged stu model, containing three vector multiplets, can be obtained as a consistent truncation of eleven-dimensional supergravity compactified on a 7-sphere [1]}, [2]}. A special subcase is the so-called t\(^3\)  model, where the three vector multiplets are identified and which will be considered in this work.
